SPECIFICATION formingpart of Letters Patent No. 593,243, dated November9, 1897. Application tiled March 1l, 1896. Serial No. 582,720. (Nomodel.)

To all whom it may concern: n

Be it knownV that we, PAUL SCHNEIDER,

HENRY TEENKAMP, and BERNARD A. GEU- RINK, citizens of lthe UnitedStates, and residents of Cleveland, county of Cuyahoga, and

State of Ohio, have invented certain new and useful Improvements inHydrocarbon-Burners, of which the following is a speciication,

the principle of the invention being herein 1o explained and the bestinode in which we have contemplated applying that principle, so as todistinguish it from other inventions.

The annexed drawings and the following description set forth in detailone mechanical form embodying the invention, such detail constructionbeing but one of various mechanical forms in which the principle of theinvention may be used.

ln said annexe-d drawings, Figure I reprezo sents a side view of ourimproved hydrocarbon-burner; Fig. Il, a vertical section of a portion ofthe bent supply-tube, the needlevalve, and drip-gage on the line Il Ilin Fig. IV of the burner; Fig. III, a vertical section on the line IllIII in Fig. IV of the burner; Fig. IV, a top plan view of the burner;and Fig. V, a transverse section looking upward from the line V V inFig. I and illustrating the drip-cup, the remainder of the burner beingomitted.

The hydrocarbon liuid is supplied to an axial tube A of the burnerthrough a suitable couplingA,connectedto thehydrocarbon-reservoir orother source for the fluid. A tube a of smaller diameter than the axialtube extends downward against the upper side of the axial tube andcommunicates with the same at the upper end. Said small tube has alaterally diverging lower portion a', which merges into a j eti-nozzleco2, which is regulated by means of an ordinary needle-valve A2, havinga suitable hand-wheel A3 or other means for rotating it. The j et-nozzleis furthermore provided with a downwardly-proj ecting driplip 0.3. Thejet-nozzle registers with the open end of a tube B, which is doubledupon itself. The open end of the tube is formed with an enlargement o,which widens outward and downward. The other end of the tube enters theburner proper, C. Said burner is annular, and the end of the doubledtube enters the annular burner upwardly at a tangent, so that mingledair and gases which pass through the doubled tube may enter the annularburner and receive awhirling helical upward movement which will carrythe air and gases to'all points of the burner.

The top of the burner consists of an annular'domed burner-plate C', theupper side of which is formed with radiating kerfs c,through which themingled air and gases escape, and the central portion of said plateextends downward to form a iiange c, which surrounds the upper portionof the axial tube and has horizontal kerfs c2, through which flame-jetsmay issue and heat the upper portion of the axial vapor-supply pipe A. Atrough-shaped fluidgage D is supported from the widened end of thedoubled tube beneath the jet-nozzle and its lip, so that fluid may dripfrom the jetnozzle down into said gage-cup. Said gagecup has adownwardly-projecting nozzle d, which is controlled by a valve d',consisting of a metal rod sliding in a cylindrical bore d2, whichintersects the nozzle. A forked block cl3 is secured upon the drip-valverod by means of a set-screw di, and said block has a guidelug d5projecting from one of its arms, which guide-lug slides in aguide-opening ZG in the vend of the drip-gage. A cam-disk D issecuredupon the needle-valve rod by means of a set-screw d7 and has itsperiphery engaging between the arms of the forked block d3. The camdiskis plane, with the exception of a short bulge d?, which diverges fromthe'plane of the disk. An annular air-space is formed around thefluid-supply tube by means of a perforated tube E and is closed at itsupper end by an annular cap e. rlhe lower end of the perforated tube issecured to an annular drip-cup F, which is secured to the axialfluid-supply tube by means of a set-screw f and is spaced from the tubeby means of radial lugs f', so that the air may enter the annular spacearound the duid-supply tube from below. The drip-cup has alaterally-projecting extension f2, which extends under the drip-nozzleof the drip-gage. A perforated cylinder E' is secured to the edges ofthe annular drip-cup and extends upward. An im- IOO ' Vthe perforatedcylinder, so as to form an anv 'nular air-space around said cylinder.vYAn' an- Y nular flame-space is thus formed above theV Vd'ripfcup, 'and'air may be Vsupplied yto both sides of saidy flame-spaeethrcughtheperfo-V thus suppliedwith air fromwvithin' and from.

o l v perforate',casing E2 isisupported from the drip-cup and has itsupper contracted end resting against ythe upper edge yof the perforatedcylinder E. yThe casing is supported rwithV its lower edge ashort'distanceabove the upper edge of the drip-cup and surroundsratedtube and cylinder, the namespace bein g Without. Y

When ythe burner is applied in similar hydrocarbon fluid and Vitisfdesired to start the burner, the needle-valve is'opened byrot-atingit nponits axis.V Thisxvillbring the plane 'portion'of thecam-disk between the arms ofthe forked block upon the dripvalve, therebypushngsaid drip-valve, so as to close theV drip -onozzle, so that thefuid' f which is projected at the jet-nozzle into the 1 open end of thecurved kpipe may flow down the inclined enlargement in said pipe into"the drip-gage and fillV the vsame vWhen the now be'ignited, and theflame Willreceive an Vairesupply'from Within andfrom Without, so l thatit Will burn With a hot and blue flame, heating the burner and the axialsupply-pipe and vaporizing the fluid in said pipe. When the burner issufficiently hot to vaporize the fluid, the needle-valve is opened andthe vaporized fluid Will rush out at the j et-nozzle into the open endof the curved pipe, Where it Will mingle With atmospheric air drawn intothe pipe by the jet of vapor and enter the annular burner with awhirling motion, which will carry the mingled air and vapor around theentire annular space in the burner.

The mingled air and vapor will escape through the radial kerfs and Willignite from the drip-cup flame. The jets Which issue from the horizontalkerfs in the annular flange of the burner-cap Will keep the upper end ofthe supply-pipe heated, so that the fluid will be perfectly vaporizedbefore it issues at the jetnozzle. The drip-gage Will admit of asufficient quantity of fluid being supplied to the drip-cup tocompletely heat the burner before the needle-valve of the jet-nozzle isturned on to supply vapor, and the cam-disk upon the needle-valve stemwill insure the closing of the drip-valve When the needle-valve isopened and the opening of the drip-valve when the needle valve isclosed, so that the exact amount of fluid may be drawn and supplied tothe drip-cup Without danger of overflowing the latter.

A smaller amount of fluid will be required a stoveand suitably connectedto a supplyfof gasolene or v for heating the burnerin thepresent formofv 1 n drip-cup and burner for the same than in the ordinary form'ofopen drip-cup, as a full sup-V ply'of atmospheric' air is fed to bothsides' of y the flame vfrom the ignited ilu-id in thedrip# Ac-up throughthe perforatedv tube rand cylinder,fwhereby an intenselyhot name isVpro-y duced.

shapeof a segment of a helix This peculiartyof construction enables usto obtain they length ofy tube required for properly mixing 1 ivould bepossible by the use ofv the circular form of mixing-chamber. `Furtherthefact that the tube enters the burner in an upward direction rhasVartiest beneficial effect, as has v o Y Vbeen found by practicalexperience. By so Y entering the vapor escapes through the kerfs moreeasily, being assisted by its own inertia, thereby reducing the pressureof the vapor upon the liquid hydrocarbon in the reservoir, and hencerequiring less heat to vaporize the said hydrocarbon, for the greaterthe pressure upon the liquid the greater the amount or' heat required tovaporize it. Thus the burner does not require so much preliminaryheating in order to start it, and consequently less oil may be used inthe drip-cup.

Other modes of applying the principle or' our invention may be employedfor the mode herein explained. Change may therefore be made as regardsthe mechanism thus disclosed, provided the principles -of constructionset forth, respectively, in the following claims are employed.

We therefore particularly point out and distinctly claim as ourinvention* l. In a hydrocarbon-burner, the combination of a drip-cup, ajet-nozzle, a dripgage beneath saidnozzle and formed With a nozzledelivering into said drip-cup, a valve for the j etnozzle, a valve forthe gage-cup nozzle, and mechanism connected to said valves andconstructed toclose the gage-nozzle valve when the jet-nozzle valve isopened and vice versa, substantially as set forth.

and formed with a cam-bulge, said cam-disk engaging the forked block,substantially as 15 set forth.

In testimony that We claim the foregoing to be our invention We havehereunto set our hands this 9th day of March, A. D. 1896.
